BALL-BEARING- FOR SPINNING-MACHINE SPINDLES.

Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed October 25, 1912. Serial No. 727,757.

To all whom it may concern:

Be it known that I, ROBERT EMIL VVAL- Tnen, a subject of the German Emperor, residing at Werdau, Saxony, Germany, have invented a certain Improved Ball-Bearing for Spinning-Machine Spindles, of which the following is a specification.

The present invention relates to ball-bearings for the spindles of spinning machines and the like, and consists in the provision, for the neckas well as for the step-bearing, of a rigid sleeve constructed as a ball cage, and of a socket which is screwed upon the sleeve so as to hold steel-balls, fitted in the cage, against the spindle, the socket having a conical bearing surface for the balls so that the latter can be adjusted relative to the spindle by a turning of the socket on its screw thread.

In the accompanying drawings the invention is illustrated, Figure 1 representing a side view of the spindle with its bearings, the latter being shown in section, and Fig. 2, an elevation of the lower ball-cage.

The neck-bearin is designated I and the step-bearing II. 0th are composed of a rigid sleeve b in which apertures are made for the reception of steel balls 0 which bear against and support the spindle a, the diameter of the latter being smaller than the internal diameter of the sleeve. On the outside of the sleeve a socket d is screwed, which socket has a conical surface with which to bear against the balls 0 for holding them 1n posltion. An adjustment of the socket d on its screw-thread adjusts the balls 0 relative to the spindle a which can thus be held steadily in its proper position while turning freely between the balls. In the step-bearing II the sleeve 1) is closed at its lower end and fitted with an additional ball 11 adapted to take the thrust of the spindle. The bearings are in both instances inclosed in a box 9 over which is pushed a cover e. The latter has an aperture h to admit the spindle and another aperture through which and through a duct 1 in the socket cl, oil can be fed into the box g. The box 9 and the cover e protect the bearing from dust.

I claim:

1. An adjustable ball-bearing for spinning machine spindles, comprising a rigid sleeve, balls held in apertures in said sleeve so as to bear against the spindle, and a socket screwed on the outside of the sleeve and adapted to hold the balls in position, said socket having a conical surface with which it bears against the balls so that the latter can be adjusted when the socket is turned on its screw-thread.

2. An adjustable ball-bearing for spinning machine spindles, comprising a rigid sleeve, balls held in apertures in said sleeve so as to bear against the spindle, a socket screwed on the outside of the sleeve for holding the balls in position and adjusting them relative to the spindle, a box surroundingthe sleeve and the socket, and a cover adapted to be pushed over the box so as to protect the bearing from dust.
